To call Vanderbilt's quarterback situation complicated would be an understatement.

Through three games this season, the Commodores have trotted out four quarterbacks.

Since there's no telling who the Gamecocks may see Saturday night, here's the skinny on the candidates to lead Vanderbilt's offense.

Patton Robinette - Sophomore

Robinette won the job coming out of fall camp, but was benched early in Vanderbilt's season-opening loss to Temple. He came off the bench and led a comeback win over UMass last Saturday.

Stephen Rivers - Grad Student

Rivers played in four game in three years at LSU, backing up Zach Mettenberger for two seasons. The younger brother of Phillip Rivers, he was 6-of-25 in a loss to Ole Miss earlier in the year.

Wade Freebeck - Freshman

Vanderbilt burned Freebeck's redshirt to have him start last weekend's game against UMass. He was replaced by Robinette in the second quarter and didn't see the field for the remainder of the game.

Johnny McCrary - Redshirt Freshman

McCrary threw an interception on his first collegiate play against Temple. He returned to the field later in the game against the Owls, only to throw another interception. He has not completed a pass yet.
